DEFINITION

Classification: 318/109

(under subclass 106) Subject matter in which one or more of the sources differs in magnitude from one or more others of

the sources.

(1) Note. Two voltages differ in magnitude when at any time one of them has a magnitude which differs in effective value from the magnitude of the other. Hence, if the magnitude of the voltage of one of the sources is varied relative to the magnitude of the voltage of another source, in order to make them different the two sources are considered to be of different magnitudes.

SEE OR SEARCH THIS CLASS, SUBCLASS:

108, for this subject matter where one of the voltage sources is an ac source and another is a DC source.

442, and the subclasses specified in the Notes to that subclass for motor systems having plural sources of supply for single motor.
